如何缓存复合服务器控件？
如何使用系统缓存对象 HttpContext.Current.Cache 在缓存中存储自定义服务器控件？
目前我的代码如下所示：
string adxkey = string.Format("adxdependency:document:{0}", this.SearchRootDocumentKey);
System.Web.Caching.CacheDependency cd = new System.Web.Caching.CacheDependency(null, new string[] { adxkey });
HttpContext.Current.Cache.Insert(adxkey, this, cd);
这位于 OnInit 方法中。我的问题是：
- 是否有更好的方法来放置缓存代码？
- 您可以像上面那样通过传递对服务器控件的引用来缓存服务器控件吗？或者我需要缓存渲染的html？
如何以编程方式缓存服务器控件的示例将不胜感激！谢谢。
How would I use the system caching object, HttpContext.Current.Cache to store a custom server control in the cache?
Currently I have code that looks like this:
string adxkey = string.Format("adxdependency:document:{0}", this.SearchRootDocumentKey);
System.Web.Caching.CacheDependency cd = new System.Web.Caching.CacheDependency(null, new string[] { adxkey });
HttpContext.Current.Cache.Insert(adxkey, this, cd);
This is located int he OnInit method. My questions are:
- Is there a better method to place the caching code in?
- Can you cache a server control by passing a reference to it as in above? Or do I need to cache the rendered html?
An example of how to programmatically cache a server control would be greatly appreciated! Thanks.

简而言之，您需要将缓存属性添加到页面或用户控件，而不是服务器控件。我写了一篇关于如何执行此操作的博客文章，您可以在这里找到它：

The short answer for this is that you need to add your caching attriutes to a page or user control, not a server control. I have written a blog post about how to do this, you can find it here:
